Ruppia maritima in reduced salinity Atlantic infralittoral muddy sand

Description (English)

In sheltered brackish muddy sand and mud, beds of Ruppia maritima and more rarely Ruppia spiralis may occur. These beds may be populated by fish such as Gasterosteus aculeatus which is less common on filamentous algal-dominated sediments. Seaweeds such as Chaetomorpha spp., Enteromorpha spp., Cladophora spp., and Chorda filum are also often present in addition to occasional fucoids. In some cases the stoneworts Lamprothamnium papulosum and Chara aspera occur. Infaunal and epifaunal species may include mysid crustacea, the polychaete Arenicola marina, the gastropod Hydrobia ulvae, the amphipod Corophium volutator and oligochaetes such as Heterochaeta costata. In some areas Zostera marina may also be interspersed with the Ruppia beds.
